HEATER OR RADIATOR.

SPEGIFIGATIONforming part of Letters Patent No. 462,337, dated November3, 1891.

Application filed May 14, 1 8 91 To aZZ whom it may concern:

Be it known that I, ALLISON J. THOMPSON, of Cleveland, in the county ofOuyahoga and State of Ohio, have invented certain new and usefulImprovements in Heaters or Radiators; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it pertains tomake and use the same.

My invention relates to an improved heater or radiator; and it consistsin certain features of construction and in combination of partshereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is an elevation in centralsection. Fig. 2 is a plan. Fig. 3 is an enlarged section of a joint F.

A represents the central member of the heater, the same comprising aconical-pointed cast-metal bar, preferably hollow at the top, in whichcase the cavity therein may serve as a water-reservoir. Outside ofmember A is a series of conical concentric tubes or shellsB O D, &c.,separated from each other so as to form air-spaces between and held intheir relative position by intermediate lugs or wings e 6, preferablycast onto the rings. The lower ends of the rings or shells taper to thinedges below, and each outer ring eX- tends somewhat below the next innerring, so that the lower end of the heater presents a concaved orinverted-cup-shaped surface, whereby the heat from the burner, that issupposed to be located directly below, is concentrated rather thandiffused by such configuration of the lower end of the heater. The heatfrom the burner or fire engages these thin edges and point of the ringsand member A, so that these soon become intensely heated, and the entirestructure eventually becomes heated to a high degree, so that thecurrent of air passing up between the rings becomes correspondinglyheated, and in such heated condition is discharged into the room. It isfound extremely difficult to obtain perfect combustion from a burner.\Vith the construction shown any gases escaping from the burner comingin contact with the heated metal and being enveloped by or commingledwith the heated Serial No. 392,774.

supporting the structure, and this ring has usually a re-enforcing bandd from whence the lugs project to give the necessary strain.

The device thus far described may be used by itself as a heater, or, ifmore capacity is required, an upper section or auxiliary heater isadded, comprising rings II I J K, &c., shaped approximately as shown, sothat the discharge is laterally, these rings being arranged inconcentric order and being usually halved onto the rings below, as shownat F. The upper sections of rings H I J K are provided with wings j j,set radially, so that the air-spaces between the different rings andnear the discharge are divided into radial air-ducts, by means of whicha lateral current of air would not materially affect the discharge ofthe heated air from the heater, whereas without such wings a lateralcurrent-of air would cause the heated air to discharge mostly at the oneside of the heater.

The overhanging sections of the upper part of the heater may be cut awayon linel Z when it is desired to set the heater close to a wall, orthese members may be cut away on lines o p 0 p when it is desired to setthe heater in a corner.

After the heater has been operation for a time, so that the entire bodyof metal has become heated, there will be a constant uniform dischargeof heated air therefrom that will not be materially affected byfluctuations of the burner, and as the heated air is dischargedlaterally it is likely to be diffused evenly throughout the room.

M is a hood that is located as shown and confines the heated air arisingfrom the burner, so that it discharges into the airspaces at the bottomof the heater.

What I claim is 1. A heater comprising a conical-pointed bar at thecenter, inclosed by a series of conirings or shells flaring outward atthe top, so as to discharge laterally, and wings between the outersections of the rings, arranged to divide the air-spaces into a seriesof radial air-ducts, substantially as set forth.

In testimony whereof I sign this specification, in the presence of twowitnesses, this 28th day of April, 1891.

- ALLISON J. THOMPSON.
